A circuit performed by a capital and meant to be a periodical process, not an individual act, is called its turnover. The duration of this turnover is determined by the sum of its time of production and its time of circulation.

Gold is now money with reference to all other commodities only because it was previously, with reference to them, a simple commodity.

The circulation of capital realizes value , while living labour creates value.

He who before was the money owner, now strides in front as capitalist; the possessor of labor-power follows as his laborer. The one with an air of importance, smirking, intent on business; the other hesitant, like one who is bringing his own hide to market and has nothing to expect but a hiding.
